Currently, the focus on the development Desanding solids control equipment , in addition to mud , gas , etc. in addition to the small footprint , high efficiency , long life equipment , and integrated with high-speed centrifuge , automatic detection and solid control system controlled by the implementation of the test results .
Performance and quality of drilling solids control system is the key to a solid phase control technology . Drilling solids control system includes drilling fluid circulating tank , drilling fluid purification equipment and electrical control equipment of three parts , in which drilling fluid purification equipment are shale shaker,mud cleaner, desander , desilter , degasser , decanter centrifuge, centrifugal pump , mud Gas separator and mud mixer , etc., for the environmentally sensitive areas , you can also configure the drill cuttings recovery and waste treatment plant.
Breakdown strength is actually cutting dryer, tilting frame 10 °, to reduce the loss of liquid. Four
solids control system
vibrating screen mesh with a three-dimensional detail of the waveform of the screen , instead of the conventional linear flat screen , three-dimensional structure allows the force of gravity down into the oncoming solid fold groove , separated from the projection area from each a fold of the upper solids separation . Therefore, by increasing the amount of fluid , the convex portion is not submerged , the convex portion can increase the fluid flow capacity. Two fine sieve cloth attached to the top layer of coarse sieve cloth , three screen cloth bonded together , made of corrugated , perforated and then bonded to the board . Waveform overlay screen area than ordinary flat screen area increased by about 40% , compared with flat screen about 2 to 3 fine sieve size . Ability to handle a 70% increase fluid and not prone to clogging , the treatment effect is very good.
In recent years , solid domestic drilling phase of theoretical research and manufacturing process control equipment has a greater level of development, especially in the study of the theory , such as shaker works, hydrocyclones works , etc., have been at or near the world’s advanced level, but made solid control equipment performance, there are aspects of life with a certain gap between foreign solids control equipment , primarily materials, processing quality , precision and supporting the use of common equipment ( eg motor) . High pressure ( pressure 80MPa), large displacement (30L / s) solid control equipment yet. Less domestic shaker type , developed in the future need to accelerate drying breakdown shaker , crawler non- vibrating sieve analysis equipment , marine environmental protection special drilling solids control equipment and versatility for a variety of conditions supporting solids control system, the rich type of solids control equipment.
